CHARLES VALENTINE SZGZYGIEL, OF AMSTERDAM, NEW YORK.

WINDOW-VENTILATOR.

Specification of Letters Patent.

Patented Nov. 17', 1908.

Application led August 24, 1908. Serial No. 450,000.

To all whom it may concern:

Be it known that I, CHARLES VALENTINE SZCZYGIEL, a citizen of the UnitedStates, residing at Amsterdam, county of Montgomery and State of NewYork, have invented certain new and useful Improvements iniVindow-Ventilators, of which the following is a specification.

The invention relates to sucli improvements and consists of the novelconstruction and combination of parts hereinafter described andsubsequently claimed.

Reference may be had to the accompanying drawings, and the referencecharacters marked thereon, which form a part of this specification.Similar characters refer to similar` parts in the several figurestherein.

Figure 1 of thedrawings is a plan view of my improved ventilator. Fig. 2is a vertical section taken on the broken line Q-Q in Fig. 1. Fig. 3 isa similar section taken on the broken line 3 3 in Fig. 1.

The ventilator comprises a triangular plate, 1, preferably of perforatesheet-metal, an open triangular sheet-metal frame, 2, secured to theperforate plate by means of the bolts, 3, and nuts. 1, an opentriangular bearing-plate, 5, of sheet-material, a little thicker' thanthe thickness of ordinary window glass, interposed between the frame andperforate plate. This bearing-plate is given approximately the same formas the triangular frame to form a seat, 6, for a cover, 7, which coveris hinged to the frame by one or more hinges, S, and adapted to swing toand from its seat to open and close the perforate portion of thetriangular pei-forato plate. rl`he cover is provided with a thumb-latch,9, adapted to lock the cover in a closed position, as seen in Figs. 1and 3. The cover is shown closed and locked in Fig. 1, with the lowerpart broken away to show a portion of the perforate plate.

The outlines of the triangular frame are similar to those of theperforate plate with each of its sides slightly shorter than thecorresponding sides of such plate, so that when the frame is superposedupon the perforate plate and secured thereto the edges, 10 and 12, ofthe perforate plate project beyond the corresponding edges of thetriangular frame, and are adapted to rest upon the window-sash at onecorner of a window pane, and be secured to the sash in any known manner,as by means of putty applied to the sash in the same way it is appliedto secure the glass.

The ventilator' may be inserted in a sash already glazed, by removing apane of glass, and cutting therefrom one corner.

Vhen the side of the ventilator opposite the right angle, 11, is curvedto form the arc of a circle, having its center at such right angle, theglass is similarly cut, so that the glass will enter the space orgroove, 17, located between the perforatc plate and the triangularframe, and its curved edge will bear against the inclosed triangularsheetmaterial, 5, which is preferably of a yielding nat-ure, as rubberor vulcanized fiber.

As a means for providing a small ventilator opening when the cover isclosed upon the perforate portion of the perforate plate, or forintroducing fresh air through a hose to different parts of the roomcontaining suoli window ventilator, l make use of a nipple, 1/1,inserted through one corner of the triangular fraiuc as shown.

The nipple may extend to a perforated portion of the perforate plate, orit may extend entirely through the pcrforate plate, as shown in Fig. 3,in which case the nipple is provided with a screen, 15. l/Vhen it isdesired to take the air to some particular part of the room, the end ofa common hose may be slid on the inner projecting end of the nipple.vWhen the hose is not applied, the nipple may, when desired, be closedin any known manner as by any ordinary cap placed thereon.

In Fig. 3, the projecting end of the nipple is shown closed by a cap,18. I have also indicated in such ligure, by dotted lines, one end of ahose, 1 6, attached to suoli nipple, the other end of the hose beingbroken away.

Vliat 1 claim as new and desire to secure by Letters Patent is- 1. In awindow ventilator, the combina- .tion with the triangular perforateplate; of

a triangular open frame; a triangular open bearing-plate interposedbetween the frame and perforate plate with its inner edges on two sides,projecting inwardly of the frame; means for securing the frame,interposed plate and perforate cover approximately fitting the openingin the frame and hinged to one side of the frame, whereby the cover isadapted to swing into and out of such opening.

2. In a window ventilator, the combinall' plate together; and a 10 tionwith the triangular perforate plate; of a triangulail open frame; atriangular open bearing-plate interposed between the frame and perforateplate with its outer edge, on one side, withdrawn from the correspondingedges of the frame and perforate plate to form a pane-receiving groovebetween the frame and perforate plate; means for securing the frame andplates together; and means for opening and Closing the opening in theframe.

3. In a window ventilator, the combination with a triangular perforateplate having two of its sides extending at right angles to each other;of a similarly outlined open frame having its three sides slightlyshorter than the corresponding sides of the perforate plate; means forsecuring the frame and plate, together with their sides, opposite theright angles of the frame and plate, in alinement with each other andthe other two sides of the frame located inwardly of the correspondingsides of the perforate plate, with a glass-receiving groove between thealined edges of the frame and plate; and means for opening and closing'the opening in the frame.

4. In a window ventilator, the combination with a triangular perforateplate; of a similarly outlined open frame; means for securing the frameand plate together; means for opening and closing the opening in theframe leading to the perforations in the perforate plate; a screenednipple inserted in one corner of the frame, and providing a passage-waythrough the frame and perforate plate; and independent means for Closingthe nipple.

In testimony whereof, I have hereunto set my hand this 18th day ofAugust, 1908.

CHARLES VALENTINE SZCZYGIEL.
